As the 2023 Women’s NCAA Championship concludes, reflecting on the swim of the meet is common. Although this is often subjective, it is hard to argue an event where three swimmers broke the NCAA record and more than 1.5 seconds were taken from the record isn’t the swim of the meet. If you aren’t aware, I’m talking about Kate Douglass’ 1:48.37 with the 200 yard IM NCAA Record.
For those who haven’t followed one of our analyses, these analyses are for fun and to spark debate. There are some inherent flaws in this race analysis:
- Videos are taken from YouTube videos (often with subpar angles)
- There are analyzed with Kinovea

Theoretical Improvements for Douglass’ 200 Yard IM
There is room to improve for every swimmer. Here are the notable improvements from Kate Douglass’ 200 IM NCAA Record:
- Most of Kate’s turns showed good timing, but her turn at the 50 yard mark was notably long (as well as Huske next to her). She was nearly fully submerged into this turn, likely slowing her 0.05 – 0.10 seconds.

- Both of Douglass’ pullouts were notably inferior to Alex Walsh next to her. It’s hard to believe the dominant 200 yard breaststroker Douglass does not have good pullouts, but she clearly rushes her dolphin kick, impeding her distance off each turn. In fact, Walsh goes a full 2.5 meters further on each pullout. If Douglass could extend her pullout by delaying her initial dolphin kick she can likely improve 0.1 – 0.15 seconds per pullout.

With these improvements, she can improve another 0.25 – 0.4 seconds.
There are likely more technical improvements with his swimming stroke, but the video from the race is not close enough or provides underwater angles for a full assessment.
